backup.sh now supports BACKUP_REMOTE_RSYNC alongside BACKUP_REMOTE. The rsync path writes <root>/YYYY-MM-DD/<archive> on the target with --link-dest pointing at the previous day's directory, so unchanged archives become hard links and daily snapshots cost almost zero extra bytes. BACKUP_REMOTE_SSH_KEY routes the rsync ssh leg to a dedicated identity (e.g. rsync.net restricted accounts). Timer moved to 03:00 Europe/Berlin (was 03:17 UTC) per #41. docs/operations.md: full restore procedure (parallel stack first, then atomic swap) plus the rsync vs rclone trade-off. Closes most of #41 — the only remaining task is the operator's choice of off-host target.
